Digital diagnosis

Michael Buckwald, CEO of Leap Motion, says he's looking forward to the day when he doesn't have to go to the doctor's office anymore -- instead the smartphone can detect if something's wrong based on how you're walking, and so on. Fitbit's James Park agrees, saying that if you collect this data and present it to your doctor, it's pretty informative about how you've been living your life. It would help the doctor better diagnose you.
